WIRE-LINE PUMPING OUTFIT FOR OIL-WELLS.

Y To` all whom it may concern:

eXact `description l thereof;

Our invention relates to wireline pumping outfits for oil wells, its object beingto provide a frangible joint adapted to be sheared where the pump becomes stuck .withinthe pump barrel, and Vso provide for the easier `withdrawal of the wire line 1 and tubing. f

These outfits aref-now employed injplawce` of the old sucker rods connected by threaded joints, as they do away'with the numerous .sectionsrequired to be secured together in vmaking upv the pumping system. The wire 1 connected to the` walking beam `passes through a sliding joint'Q at; thetop of the `well formed of`a hollow sleeve ofsuficient length for the pumping stroke and working in a suitable journal 3, and the wire eXtends `down close to the location of the pump4 j time.

"strain, this joint will part and permit the where a few metal sections 5 are added to hold the wire line taut, below which is the pump working in the pumping barrel. rlhe pumping barrel 6 is sustainedat the base of the line of tubing 7T and below the same is the pump valve 8 placed above the strainer 9 located where the oil is collected within the oil bearing strata. In the pumping action grit or sand is liable to be carried up by the oil, and where thepumping vof the oil is stoppedfor any reason, this or grit sometimes settles around the pump and within the` pumping barrel and causes the same to stick fast and resist the entire power' of the pumping engine. In such cases it is necessaryto removethe tubing and pumping line and in case the wire line remains within the tubing, this is a verydiliicult, expensive and tedious operation requiring the frequent `cutting of the wire line, the slipping of the sections o fA tubing over the wire line, etc., and oftenjoccupymg as much as a weeks By the present invention, a frangible joint is provided at or near the base of the wire line, so that under a certain pulling Specification of Letters Patent.

example, just above the pump et.l It is connected to the lower sectional weight and to the pump by a threaded pin and socket joint 1l and`12, and it is composed of a male member and a female member, these members fitting snugly with each other. The male member 13` has at its base the shoulder 14k and above the same the cylindrical body 15, while the female member has the sleeve 1G fitting over the cylindrical body and abutting against the shoulder 141 of the male member'. The two members are provided with a series of rivet holes which register `with each other,the male member having the rivet `holes 18, and the `sleeve `member having the rivet holes 19. Through these rivet holes the rivets 20 pass to hold the two sections against longitudinal separation, and

the number and size of rivets employed depend upon the weight of the tubing and the force necessary to break the clamping grip and cause the shearing of the rivets. To this end, we prefer to employ rivets of great tensile strength, the drawing showing a series of larger rivet holesA 18 and 19 and therivets 20, and also a second series Aof like rivet holes 2l of smaller diameter, requiring smaller rivets.y The sleeve 16 is slitted from its base to the end of `its bore, as at 22, to provide for the clamping of the sleeve upon the male body portion by the `upsettingof the rivets, forming in this'way For example, it is l Thus, in making up the joints the number f and size of rivets to be employed and the n character of the rivets can be ascertained according to the weight of the line of tubing, it being desired that. theV lclamping. grip of the sleeve be such asfto prevent play between the parts and to sustain all ordinary pumping shocks and strains, and yet will yield before the strain is sufficient to raise the tub- .ing in the well, this being a matter of calculation according to its depth, which'usually varies'from Y,1000 to 4000 feet.

When the invention is in'use, the pumping operation is followed in the ordinary way,

operation the frangible joint transmits the power without allowing 'any play of the parts, the base of the sleevel fitting firmly against the shoulder 14 of the 'pump section 13 and the frangible joint` therefore providingy forvpositive transmission of the power on both the up and down strokes of the rump- In case the pump becomes stuck in the pumping barrel, such, for example where the sand or grit is carriedjinwith the oil i and the pumping operation ceases so that this sand orgrit will pack around the pump and H stick it fast, the operator may overcome this condition by applying heavy power to the pumping line `and start the pump; but if this proves impracticable, he applies suiiicient force'to cause the shearing of the rivets in the frangible joint, and so frees the wire line from the pump. In this operation the power to be applied is less than that required for the raising of the tube, else the frangible joint., would not perform its function without anchoring down the tubing. VAccordingto the known weight of the line of tubing the number and character of rivets employed isiiXed and when the power necessary to shear the rivets is applied, the wire line parts from thepump leaving it within the well. .The wire line can then be easily .withdrawn from the well, and the well tubing can also be easily and quickly withdrawn, separate and independent from the wire line, whereas the necessity-of performing this op- I eration with the wire line within the tubing,

.j during the withdrawal of the tubing.

would necessitate the slipping of the tubing over the wire line or cutting of the wire line The frangible joint can be arrangedy for re-use simply by the insertion of new rivets.'` What'weclaim is:

1. The combination with a wire line pumping outfit, of a telescopic frangible joint, each member of which has terminal yabutment with the other, and a series of clamping rivets uniting them.

2. The combination with a wire line pumping outfit, of a cylindrical telescopic joint, each member of which has terminal abutment with the other, and a series of fraiigible rivets uniting them, the rivets being adapted to be sheared under known strains.

3. 'Ihe combination with a wire line pumping outfit, of a cylindrical telescopio joint located therein and formed of male and female'members, each having terminal abutment with the other, the female member having a slot extending longitudinally the length of its bore, and one or more frangible clamping rivets for clamping the female member upon the male member, said rivets adapted to shear under a predetermined load.

i 4. The combination of a line of well tubing carrying a pumping barrel at the bottom, a wire pumping line carrying' a pump at the bottom working within the pumping barrel, and a telescopic frangible compression joint between'the wire and pump adapted to yield under a predetermined heavy strain.
